Wikipedia Google Earth layer

Hi,

I was wondering if anyone here knows how often does Google update
their Wikipedia layer for Google Earth and how do they get the data? I
mean, they use the geo templates in the articles, but do they parse a
wikipedia dump or they use a crawler or some other method.

I'm not sure if Wikimedia has anything to do with it, but I think I
have a better chance of getting an answer here than by asking Google
(the company) directly. Google (the search engine) was not really
helpful on the matter.

Thanks,
Andrei

you could always install Ethereal, and spy the trafic from your
computer to the network. It probably include some HTTP servers, and
GET / POST request you can read.

That would mean assuming that the data is gathered on-the-fly, which I
strongly doubt. I am more inclined to think that Google has some
periodically updated database with the coordinates-articles
relationship.

I'd be very surprised if they did anything other than crawl. They're
good at crawling and don't like making exceptions*. And en dumps are
pretty unreliable - they could be months out of date.

I'm pretty sure ethereal was renamed to wireshark a while back...

The LiveHTTPHeaders extension for Firefox will also do this job for
you, and is a bit easier to install and use.

Re: Wikipedia Google Earth layer [In reply to]

I think Google applications use the data crawled from their own datbases and
of course Google has almost all last updates of Wikipedia articles with all
its information including the Geo addresses.

They use the dumps, and they reported some time ago to do so about once
a month.
For other questions, you could try contacting with Jason.

I guess so :)

Thanks for the info, Platonides. I'll try to contact Jason to see what
else can I find out.
